CHARLES L. HEISLER, OF ST. MARYS, OHIO.

T 0 all whom it may concern.

Be it known that I, CHARLES L. HEISLER, a citizen of the United States,residing at St. Marys, in the county of Auglaize and State of Ohio, haveinvented certain new and useful Improvements in Churns of the Rotary-Dasher Type, and which are described in the following specification andillustrated by the accompanying drawings.

Figure 1 shows a longitudinal elevation. Fig. 2 shows an end elevation.Fig. 3 shows a vertical cross section. Fig. '4 shows a top view. Fig. 5shows a section of the enlarged stave. Fig. 6 shows a section of thecross piece.

The primary object of my invention is to provide a more effective anddesirable construction and arrangement of driving gear and to provide amore durable and readily cleaned churning chamber.

Heretofore it has been usual to construct barrel churning chambers witha contracted opening, which would not readily permit cleaning orremoving the butter from the churn. Furthermore, in rotary dash churnsit has been usual to construct a chamber hav ing a very large opening inthe top and therefore requiring a very large lid, which, because of itssize, was expensive and readily warped. Moreover, this old form of churnwas diflicult to keep tight. In this new construction the maximum volumeis obtained with a minimum expenditure of material like in the barrelchurn, at the same time, however, it gives accessibility with mediumsize of opening, thereby avoiding the objectionable feature of the oldertypes of churns.

I-Ieretofore, it has been impossible to put grease 011 the churn gearsbecause of the danger to clothing and to the contents of the churn.Moreover, considerable injury has been caused by the unguarded gears tochildren and clothing. These defects are eliminated in the new device aswill be shown hereinafter.

In the several figures, numeral 1 is the churning chamber. 2 and 3 thestaves form ing the cylindrical wall. 4 and 4 the end heads that fit ingrooves formed in the staves. 5 the lid.

The churn chamber 1 is supported upon a tripod formed by the legs 6 andthe supporting casting or keel 7, upon which are formed sockets or lugsto secure the legs as shown. A drip catching lip 8 is formed upon thiskeel Specification of Letters Patent.

casting, likewise several lugs 9; these have suitable holes to retainthe adjustable hoops or rods 10 and 10 which are fitted with ad justingnuts or screws 11 as shown. These rods, in combination with the saidtripod, form a very rigid and strong support for the chamber. The rodsalso form a ready means for adjusting the tightness of the churn.

' The staves 3 are especially constructed with an enlarged upper edge asshown in Fig. 5 to give a strong rim for the opening. The rods 10 aremade to pass through holes 12 that are drilled through and near theupper edge of the staves 3, thence said rods pass between the heads'4and 4, and the cross pieces 13. The latter having a suitable retaininggroove formed on their under side to inclose the rods as shown. Theopposite ends of the rods 10 meet at the supporting keel 7 and therebyform complete adjustable hoops that tightly hold the staves and heads inplace. The short rods 10 terminate in the staves 3 as shown in Fig.3 andFig. 5. The cross pieces 13 are fastened by screws to the'heads 4 andbutt at right angles against the staves 3, forming a strong and completerectangular rim about opening, at the same time protecting the ironhoops or rods from contact with the contents of the chamber.

The dasher 14 is of usual construction, 6X- cepting that an enlargement15 is formed on the upper end of its wooden shaft as shown in Fig. 1 toprevent the liquids from splashing through the opening 16 and to avoidslipping through the operators hand when inserting it into the flangedspool 17. This spool is flanged for the purpose of preventing oil fromflowing into the churn from the spindle bearing 18. To further preventthis, a wiper 19 is placed in contact with the flange of the spool asshown in Fi 1.

At the upper end of the inclined dasher spindle is arranged a bevelpinion 20 that is actuated by meshing with the internal bevel Wheel 21,which is operated by any suitable crank or power. This internal bevelwheel is mounted upon a removable pin 22 that is removably fastened tothe gear bracket 23. The internal wheel 21 is cast preferably withoutspokes, so the pinion 20 is com letely guarded by the oil tight saucershapecl internal gear wheel. The bracket 23 also forms a shield at theback of the gear, thereby forming a complete protection against injuryto children or clothing.

A lip 24 collects any drippings from the bearings and returns them intothe internal gear wheel, the axis of which forms an acute angle with thedasher shaft or spindle as shown. Lugs 25 are formed on the bracket 23to more firmly hold the gearing on the churn.

In Fig. 1 it will be seen that when the crank handle is carried bygravity to its lowest and natural position, the thumb nut or clampingscrew on the spool 17 is in its upward and most accessible position.This saves a great deal of annoyance when removing or replacing thedasher, and is effected by having the number expressing the pinion andgear teeth ratio a whole number, for example, as 3 to 1, and by settingthe gears as shown.
